the answer is since the the angle on the inside of the triangle is 90 degrees by supplementary angles and the other angle that is not p is 47 degree, also by supplementary angles. Thus you take 90+47=137 and subtract it from 180 since that is is the total angle sum of a triangle and you get 43 degrees or answer b

180 - 133 = 47 (supplementary angles; sum of 2 angles is 180)

180 - 90 = 90 (supplementary angles; sum of 2 angles is 180)

All 3 angles in a triangle must add up to 180 degrees.

90 + 47 = 137

180 - 137 = 43

43 degrees is the value of p (B).
